Thesis Title
Segmental Morphology of Perennial Ryegrass (Lolium perenne L.) : A Study of Functional Implications of Plant Architecture

Looking at the form and function of perennial ryegrass plants at the growing unit level Mr Robin freshly described the detailed structural organisation of the ryegrass plants and functional relations of their growing units. ‘Rate of growing unit formation’ on the grass tiller axis between spring and autumn seasons and their differences due to seasonal weather variation; and a time lag in leaf and root production at the same ‘growing point’ as determined by the grass tiller architecture, modified the root and shoot dry matter balance. Daughter tillers were essentially important in feeding older roots of parent tiller which were of the same or neighbouring in origin. A significant amount of new knowledge on root development pattern and root system morphology of ryegrass plants generated from this research.
